(only if it would be taught as a separately required course).［/ｕ］ ffice ffice" />
A. only if it would be taught as a separately required course
B. only if it is taught as a separate, required course
C. if it is taught only as a course required separately
D. if it was taught only as a separate and required course
E. if it would only be taught as a required course, separately
Choice B is best: in sentences expressing a conditional result (x will happen if y happens), the verb of the main clause should be in the future tense and the verb of the if clause should be in the present indicative. Thus, is taught (in B) is consistent with will take, whereas would be taught (in A and E) and was taught (in D) are not. For clarity, only in C, D, and E should immediately precede the entire if clause that it is meant to modify. Also, the intended meaning is distorted when the adverb separately is used to modify required, as in A and C, or taught, as in E; B correctly uses the adjective separate to modify course.
本题的正确的答案是B,但是我觉得B在separate, required 之间加一个and才合适,,难道两个形容词并列不需要加and吗?
为何在这儿用了一个逗号呢?是不是separate, required course 等于separate and required course呢? |
